Light distribution system and method for large depth of field mirror image tail light

Abstract

The application discloses a light distribution system of a large-landscape-depth mirror image tail lamp, which comprises a lamp shell, a PCBA is arranged on the inner cavity bottom surface of the lamp shell, an annular LED lamp is arranged on the PCBA, a side light shielding ring is arranged near the center side of the LED lamp, an annular cylindrical lens is arranged between the lamp shell and the side light shielding ring, end surfaces 1, 2, 3 and 4 are arranged on the annular cylindrical lens, a top light shielding ring is arranged on the top of the annular cylindrical lens, a half lens is arranged on the top of the top light shielding ring, and a lamp cover is arranged on the half lens and is in sealing connection with the lamp shell. The application also provides a light distribution method of the large-landscape-depth mirror image tail lamp. The novel structure plans the propagation path of light, reduces the transmission loss of light, improves the diffusion degree of light and the intensity of the single-surface mirror full-reflection light, increases the mirror reflection times of light by optimizing the transmittance ratio of the half lens light splitting film, further increases the landscape depth of the light distribution light type, and makes the light type have stronger vertical depth.
